Doug Mcknight of the Yellowstone Angler in Livingston, Montana, holds this 6 pound rainbow caught on the Chubut River in Argentina last month. Doug took his Simms gear on the long journey south, including his G3 Guide™ Waders, Simms 406 hat and Freestone Boots with StreamTread™ soles from Vibram®. How did the new boots fare down in Argentina? "My new Vibram Freestones were Awesome!" proclaims Doug.
